' TRACTION-.WHEEL.

To all wkomz'tmay concerm Be .it'knownthat I, J OHN G. VINCENT, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful 1' Improvements in Traction-Wheels, of which the following is a specification.

This invention relates to improvements in:

traction wheels especially adapted for use on motor trucks-tractors and other vehicles.

An important object of this invention istoprovide a traction wheel having a plu-' rality of radial fins' secured to one side and terminating adjacent the tread'of the same whereby in the event of the vehicle'to which thewheel is appliedencounterin'g amuddy orsandy road, .theradial'fins will be brought into contact with the ground for'afiording a positive gripbetween the 'wheeland the ground.

A further object of from the wheel whereby said fins are tapered A further object of the invention is to provide a traction wheel having a plurality .of radial fins "terminating inwardly of the treadof the wheel'so that thesame'will come into play only'when the wheel becomes em bedded in mud or sand.

' Agjfurther object of the invention is to providea wheel of the class describedzwhich is; simple,-efiic'ie'nt in use and comparatively cheap to manufacture. Other objects and advantages. of the invention will be apparent duringthe course of the following description.

-.In the accompanying drawings forming a part ofzthis. application and in whichlike=- this invention-is to; provide a traction wheel having a plurality ofradial fins mounted on ai conical base: plate having its apex extending outwardly Wheel: i

In the drawings wherein for the purposev of illustration 1s shown a preferred embodiment of the invention, the numeral 10 designates a rear axle housing of a truck, a pleas ure vehicle,*or a tractor as the case may be.

As illustrated in Fig. 1, traction wheel s genvidedwithcentrally arranged openings 15 through whichdriving axles of the truck may-extend. As any suitable means may be employed for rigidly connecting the wheel to an axle whereby the wheel will rotate with the axle, detailed illustration and llescrlption ofthis feature is deemed unneces- (sary.

about the fixed'rim' band 14 is designated generally by the-numeral 16 and includes a transversely curved annular tire receiving portion 17 18-have their inner edge portions bent inwardly upon themselves as indicated at 19 for strengthening and reinforcing the rim against lateral' 'and circumferential thrust. As illustrated tin: Fig. 3, the rim 16'is snugly arranged about the fixed rim'band 1 1 and one- .flange18 ofv the sameengages a peripheral retaining flange 20 formed by extending the edge, portion of the disk 12 beyond the fixed rimband@l4 and offsetting the samelater ally. Whenthe rim-16 has been snugly arrangedon the felly and engaged withthe re- I tainingzflange 20 a conical base plate 21 of a diameter equal to the diameter of the'wheel .is arrangedabout the other side of the wheel and a peripheral flange 22 carried by the same is engaged with the other inwardly extending flange 18 of the rim. As will be noted from reference to Fig. 3, the flange 22 extends beyond the fixed rim of the wheel and engages the rim for securely retaining the same in position. The fixed rim band 14 is provided with a plurality of spaced transversely extending semi-circular rethrough the axle hous-h having inwardly extending flanges 18. The inwardly extending flanges their inner edges Bout-away slightly as in;

cesses 23 with which pairs of spaced transversely extending semi-circular recesses24: in the flanges 18 are adapted "to 'register'fdr the reception of retaining bolts 25. The

retaining bolts 25 also extend throughspaced openings 26 in the flanges 22 and through openings 27 in the retaining' flange20'Whereby the rim is securely held on the fixed rim band and prevented from circumferential movement wi-th relation to the fixed rim band?v d r v .c

It might be stated at this point that the rim 16 may be providedwith artread or tire.

It is to be understood that the form, of

the invention herewith shown and-described is to be taken as apreferred embodiment of the same and that such minor changes may be made as will remain within the spirit of the invention and the scope of what is claimed.
